Abstract
Description
- This application claims the benefit of priority to Korean Patent Application No. 10-2015-0140931, filed on Oct. 7, 2015 with the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
- The present disclosure relates to a power distributing apparatus of a vehicle, and more particularly, to a power distributing apparatus of a vehicle in which a junction block is electrically coupled directly to peripheral components.
- Generally, a vehicle is provided with a junction block in order to prevent an excessive level of current from flowing to various electronic components. Fuses, blocking a circuit are instantaneously fused when a current of a predetermined numerical value or more flows thereto, and relays, that operate when an input value arrives at a predetermined value to open and close another circuit, are accommodated in the junction block.
- The junction block includes about twenty to forty fuses and about ten relays even though the numbers of fuses and relay may be slightly different depending on sizes and types of vehicles. When the fuses and the relays are dispersed, a structure of the fuses and the relays may be complicated, and control of the fuses and the relays is difficult. Therefore, the junction block is used to integrate the fuses and the relays in one place and/or device to distribute power in each mode.
